1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

objectivesHealthcare contributes considerably to greenhouse gas emissions, particularly from operating theatres. The global demand for total hip replacements (THR) is rising, highlighting the need to understand its impact on the environment. The study aims to assess the environmental impact of THRs using life cycle assessment (LCA) and to identify key contributors.

designA process-based LCA focusing on the surgical procedure was conducted in accordance with global standards (ISO 14040:2006 and ISO 14044:2006). Eleven sensitivity scenarios were performed to assess the robustness of the results.

settingA Danish University Hospital.

participantsThe empirical data involved the quantity and type of surgical equipment, material composition, energy usage and clinical infrastructure. There were no study participants.

interventionsNo study interventions were performed. PRIMARY AND SECONDARY OUTCOME MEASURES: 18 environmental impact scores, such as global warming, human toxicity and water consumption, were assessed.

resultsThe carbon footprint of a THR was 62.0 kg CO

conclusionTHRs impose a substantial environmental burden, and sustainable solutions should focus on the primary drivers of this impact: disposable utensils, implants and the sterilisation process. In contrast, clinical infrastructure and non-disposable utensils appear to have a relatively minimal environmental impact.
